Develop tools for internal use to make the life of colleagues easier.

Python developer

Worked as a Python developer on a Django project.

Senior Python developer

I worked with Python as a student (in computer science) and later started to develop some expertise in it through my work as a data scientist and technical lead developer.

Python was used for machine learning tasks (training models, testing models, making predictions), computer vision (detecting teeth from X-ray scans), fast algorithm design, database manipulations (SQLAlchemy), webserver development (flask), etc.

On StackOverflow, I answer questions about Python on a daily basis.

I learned Haskell as a college student and used it for fast algorithm development on several programming contests.

Through the years I mastered less easy topics like for instance monads. I also wrote a user interface that uses curses.

Learned Java myself and used it for a lot of courses as a student and to build some servers.

Java was the de facto programming language in college (KU Leuven) and was used to master concepts about networks (UDP/TCP programming), servers, distributed systems, operating systems, and building a 3d rendering engine.

The first programming language I learned. I used in for a lot of hobby projects including desktop applications, rendering engines, machine learning, algorithm development.

I used databases for both toy-projects and in a working environment. PostgreSQL was used to develop a web application for a student association and I used MySQL in a working environment in an AI startup.

Prolog is a programming language one can use for fast prototyping of constraint problem solving. I used it to solve some problems including sudoko and hashiwokakero. I have some experience in ECLiPSe (constraint logic programming, not the IDE) and CHR (Constraint Handling Rules).

I also wrote a small Prolog interpreter.

I frequently design my own algorithms for problems. Usually time and space complexity are important factors as well: one wishes to process huge amounts of data.

On programming contests (Flemish Programming Contest, IEEEXtreme, Benelux Algorithm Programming Contest, North-Western European Programming Contest, ...) I designed (together with several teams) algorithms. Usually we did reasonably well.

I specialized in Artificial Intelligence during my studies as a computer science engineer. During a short career as an AI researcher I developed some models based on hidden Markov models. I later worked as a data scientist and technical lead developer in an AI startup.

In my experience most data scientist simply start training a model, without any knowledge about how that model works internally. As a result, one gets dissapointing results, because they aim to train the model with data the model cannot represent accurately. Therefore it is important to have a basic understanding about the differences between the different machine learning techniques.

I learned Django while working on an accounting application for lawyers. I wrote two Django packages (django-single-sessions and django-enforced-choices), and currently am finishing another package.
